Answer:
(2, 3)
Step-by-step explanation:
2x + 5y = 19
5y = -2x + 19
y = 
P(abscissa, ordinate)
P(x, 1.5x)
P(2, 3)
3 = 15/5
3 = 3
Answer:
You must divide 
by 
Step-by-step explanation:
we have
Step 1
Solve for x
Step 2
Find the value of y
Substitute the value of x
therefore
You must divide by
The polynomial cannot be factored in because it exists prime. Since 112 exists not a perfect square number so we cannot estimate the factors of the given equation.
<h3>What is a quadratic equation?</h3>
In a quadratic equation ax² + bx + c = 0
when (b² - 4ac) exists a perfect square only then we can factorize the equation.
In the given equation x² - 8x - 12 we have to determine the value of
b² - 4ac
From the equation, we get b = -8 and c = -12
b²- 4ac = (-8)² - 4(1)(-12)
= 64 + 48 = 112
Since 112 exists not a perfect square number so we can not estimate the factors of the given equation.

Answer:
x-8<-15
Step-by-step explanation:
1) Those are polar coordinates
2) The expression inside cosine is the angle of the vector to be drawn
3) r is the length of the vector to be drawn.
For example:
- if you take angle =0 and r results to be =2, it means that you have to put a point over the x-axis at a distance of two units from the origin.
4) You have to look for notable values, like points on the axis and notable angles (0, 45°, 90°, 180 °,...)
5) Use derivation to find maximum and minimum values.
6) The graph of this function looks like the infinite symbol: ∞
7) Some notable points are: (0,0) ; (0,2) ; (0, - 2)
See attached the complete graph as a reference.
